Shimano Dura-Ace 12-Speed Power Meter Crankset

The Shimano Dura-Ace 12s crankset with power meter is designed for road cyclists who want to measure power directly at the crank arm, without additional sensors. The meter has an accuracy of ±1.5 % and the crank arm follows the Hollowtech II standard, with a 24 mm axle and a 68 mm BSA shell: check that your frame is compatible before buying.

It is designed for the Shimano 2x12-speed drivetrain and has aluminium arms with a steel axle. To choose between the 34-50 or 36-52-tooth chainring combinations, consider the terrain you ride most often: smaller chainrings provide easier climbing gears, while larger ones favour higher speeds. The pack includes the 1,5 m EW-EC300 charging cable for the meter.

Founded in 1921 in Sakai, Japan, by Shozaburo Shimano, Shimano is still based in the same city today. For cyclists, it makes drivetrains, brakes, wheels, pedals and cycling shoes. Its history in bicycle components began with the production of freewheels in 1922.
